Trichodermadiones A and B from the solid culture of Trichoderma atroviride S361, an endophytic fungus in Cephalotaxus fortunei

Chemical investigation on the solid culture of Trichoderma atroviride yielded a pair of novel N-furanone amide enantiomers, (−)-trichodermadione A (1a) and (+)-trichodermadione A (1b), and a new cyclohexenone sesquiterpenoid, trichodermadione B (2).76
